W16155A_Pure_Cytokeratin7_1_WB_Antibody_081717
Total cell lysate (15ug protein) from HaCaT, A549, MCF-7 (negative control) and NIH3T3 cells were resolved by electrophoresis (4-12% Bis-Tris gel), transferred to nitrocellulose, and probed with 1:250 (2 µg/mL) diluted purified anti-KRT7 antibody (clone W16155A) or competitor’s antibody used at manufactures recommended concentration (upper). Proteins were visualized by chemiluminescence detection using 1:3000 diluted HRP rat-IgG secondary antibody conjugated to HRP (clone Poly4054) for clone W16155A or 1:3000 diluted donkey anti-rabbit IgG Antibody conjugated to HRP (clone Poly4064) for competitor’s antibody (upper). 1:2000 dilution of Direct-Blot™ HRP anti-β-actin antibody (clone 2F1-1) was used as a loading control (lower). Lane M: MW ladder, M* indicates longer exposure.

    HaCaT cells were fixed with 4% paraformaldehyde (PFA) for 15 minutes, permeabilized with 0.5% Triton X-100 for 3 minutes, and blocked with 5% FBS for 60 minutes. Then the cells were intracellularly stained with 1:250 diluted (2 µg/ml) anti-KRT7 (clone W16155A) antibody overnight at 4 degrees followed by 1:250 diluted (2 µg/ml) Alexa Fluor® 594 (red) conjugated goat anti-rat IgG (clone Poly4054) antibody for one hour at room temperature. Nuclei were counterstained with DAPI (blue). The image was captured with a 60X objective.

Description

Keratin 7 (KRT7) belongs to type II keratin and is expressed in the epithelia lining the cavities of internal organs, gland ducts and blood vessels. The function of KRT7 is still not clear but it has been suggested involved in the translational regulation of the human papillomavirus type 16 E7 mRNA (HPV16 E7). In cancer, the expression of KRT7 is observed in many types of carcinoma and is associated with neoplasm progression. The diverse and unique expression pattern of KRT7 is often used as a diagnosis indicator in epithelial origin carcinoma. For example, aberrant KRT7 expression is observed in triple negative breast cancer. In bladder cancer, loss of KRT7 results in promoting proliferation of the bladder urothelium.
